Partclone 0.3.5a fails to build against RHEL/CentOS 6 on ppc64 (only)

Partclone 0.3.5a fails to build against RHEL/CentOS 6 on ppc64 (only), it works on other architectures, such as i686 or x86_64.

main.c: In function 'main':
main.c:845: warning: format '%08llX' expects type 'long long unsigned int', but argument 3 has type 'off_t'
make[2]: *** [partclone_xfs-xfsclone.o] Error 1

Even the (re)definition of umode_t in xfs/platform_defs.h:50 is wrapped using HAVE_UMODE_T, there is no code ever testing for the existence and setting the definement via ./configure accordingly. Setting CFLAGS=-DHAVE_UMODE_T for ppc64 builds on RHEL/CentOS 6 myself works around the issue.

This is no longer relevant for me, because Red Hat Enterprise Linux 6 (including its derivatives) reached its End of Life already at November 30th, 2020 – and so did EPEL 6, which I am building and packaging partclone for.
